I have just uploaded the archives for a new luatex release, 0.74.0.

Most noticeable changes:

* Lua 5.2
   There are no patches to the core Lua files; a future version
   of luatex will switch to loading the regular lua 5.2 dynamic
   library instead of depending on a statically compiled

   NOTE: This change can break some of your lua files, as the
   language has changed a little between versions 5.1 and 5.2

* A bleeding-edge version of luasocket is included, as there
   is no 5.2-compatible official release yet.

* A new lua extension is the two-argument version of
   string.dump from Luajit:

     string.dump(function f, [boolean strip])

* Included mpost 1.780

* The implied existence of the following Lua libraries is now

      debug, unicode.*, luazip, lfs, lpeg, zlib, gzip, md5,
      socket.*, profiler, epdf, fontloader, mplib, and

   Future versions of luatex will load these modules on demand
   from dynamic libraries.

   Please update your sources to include a 'require' line for
   each of the library modules mentioned.

* Two new callbacks: find_cidmap_file and load_cidmap_file
   (used by the fontloader to discover .cidmaps)

The archives can be downloaded from supelec as usual:
